In a JT-60SA project, JT-60U is repaired to superconductivity tokamak JT-60 SA as a satellite tokamak plan by "broad approach (BA) activities towards realization of the early stage of nuclear fusion energy" who carries out by Japan-Europe cooperation. JT-60SA is built in the torus hall of a JT-60 experiment building main part after demolition of JT-60U equipment. In JT-60 SA, arrangement examination and an interference check are performed about the apparatus of the structure which becomes intricate intricately using a 3D-CAD model. A plan for the three-dimensional measuring instrument (laser tracker) which is leading-edge technology to perform position measurement is carried out. The laser tracker is highly precise as compared with the usual measuring instrument, and can make a fabrication error small as much as possible. A lecture describes position measurement together with an assembly procedure.
